LifeScan is recalling blood glucose meters that shut down at extremely high glucose levels and fail to provide a warning, the company announced.

LifeScan is recalling blood glucose meters that shut down at extremely high glucose levels and fail to provide a warning, the company announced.

At readings of 1,024 mg/dL and above, the units can fail to alert the user and may simply power down instead, putting patients at risk for serious adverse events, according to a statement from LifeScan.

In the U.S., the affected model is the OneTouch Verio IQ meter. About 90,000 models have been sold here, but no adverse events have yet been reported.

The recall also extends to similar OneTouch devices sold in Europe, the Middle East, and Asia, including the Verio IQ, Verio Pro, and Verio Pro+.

LifeScan reported one serious adverse event outside of the U.S. with the Verio Pro meter, but it hasn't been determined whether the meter was a causal factor in the event.

Although the likelihood of experiencing such a high blood sugar level is rare, when it happens it is a "serious health risk requiring immediate medical attention," the company said in its press release.

It advised patients to contact LifeScan customer service in order to get a free replacement meter, and said patients can continue to use the Verio IQ model until the replacement arrives -- as long as they are aware that a shut-down could indicate dangerously high blood glucose levels.
